Abstract
Objective
We describe a novel and efficient CT biopsy technique that we have termed ‘skin adhesive and hand-aided biopsy technique’, shortened to the acronym SAHNA. This technique is ideal for biopsying surface osseous lesions where there is a lack of subcutaneous fat. This avoids the need for the radiologist’s hand to be in close proximity to the CT scanner beam at the time of intervention.
Methods
The SAHNA technique uses a plastic surgical forceps towel clamp to stabilise the biopsy needle just proximal to the lesion after piercing through the skin. The clamp itself is stabilised via a self-adhesive dressing which is stuck down to the skin at its shank.
Results
In our institution, we have already used the SAHNA technique successfully in over 5 cases.
Conclusion
The SAHNA technique is a widely accessible and effective way of stabilising the CT biopsy needle in technically challenging superficial bony lesions.
